Anomalous number of Google Cloud Storage Objects Accessed



Detect when a Google Cloud identity accesses a number of Google Cloud Storage objects that they do not usually access.


Monitor Google Cloud Audit logs to identify when a Google Cloud identity makes an anomalous number of storage.objects.get calls to a unique number of Google Cloud Storage buckets (bucket_name).

Triage and response

  1. Determine if the user: {{}} should be accessing the storage buckets.
    • Here is a list of buckets that were accessed (up to 10): {{bucket_name}}
  2. If the action is legitimate, consider including the user in a suppression list. See this article on Best practices for creating detection rules with Datadog Cloud SIEM for more information.
  3. Otherwise, use the Cloud SIEM - User Investigation dashboard to see if the User: {{}} has taken other actions.
  4. If the results of the triage indicate that an attacker has taken the action, begin your company’s incident response process and investigate.
